1、在Fluent中采用TUI设置周期性边界的方法ByZjz(1)首先，指定计算域的RotationalAxis(CellZoneConditions中，FrameMotion)(2)其次，对响应的组件进行周期性设置，命令为：/mesh/modify-zones>make-periodicPeriodiczone[()]13Shadowzone[()]14Rotationalperiodic?(ifno,translational)[yes]yCreateperiodiczones?[yes]yzone14deletedcreatedperiodiczones.(Whenyo

3、eusingthemesh/modify-zones/matching-tolerancetextcommand,butitshouldnotexceed0.5oryoumaymatchuptheperiodiczonesincorrectlyandcorruptthemesh.)(3)然后，检查周期性边界条件是否设置成功(菜单栏：mesh/check)。周期边界设置失败时，Fluent提示：WARNING:rotationinconsistentonzone9.Pleasecheckperiodicsetup.可以采用如下命令进行修正：/mesh/repair-impr
